Temporal Estimation- Time Feedback

I would like to build an experiment where one has to press a space bar when it comes to five seconds since the start of the event.(subjectively).

The problem is I would like to give time feedback to the participants of how fast/ how slow they have responded.

For example, if they responded 1’30" earlier than five seconds, presenting feedback saying - 1’30" would work.

please help me out on this.

Thanks in advance.

Attached is an experiment that calculates and presents how fast or slow the participant has responded. It’s in the format that you’ve specified, e.g. 1’ 30".
